Biochemical composition and the elemental chemical constituents of the planktonicsergestid shrimp, Lucifer hanseni Nobili were estimated during October1991 - May 1992 from a selected station off \^pin island in the Cochin estuary.Protein formed the m^or fraction of the organic constituents. Seasonal variationwas observed in the protein content. Protein and lipid fractions were inverselyproportional. Neither lipid nor carbohydrate appeared to be significant energysources. Lipid was the most variable component. An inverse relation was evidentbetween the moisture content of the shrimp and its lipid level. Carbohydratecontent of the organism was found complementary to its lipid content. Decreasein carbohydrate content was recorded during periods of low salinity. Values ofchitin and ash were less variable. There was marked seasonal variation in themoisture content. Calorific content of L. hanseni estimated as 4.527 k cal/g ashfree weight was found comparable with that of other cadidate species selected aslive feed. The average values of carbon, nitrogen and hydrogen were 39.84%, 8.73%and 6.09% respectively of dry weight.
